I been using these for at least 8 years and never had a problem with them. They changed the formula and
made the cores way too thin. They twist lengthwise much too easily and even after doubling my string height
they still buzz.
I put the first set on and I couldn't intonate the low E. It was way too flexible. and had bad fret buzz. I figured
OK one bad set out of so many, I can live with it. Second set all the wound strings were buzzing badly.
I had one older set to compare them too and its obvious the cores and the wraps are different.
They are NOT the same strings
